In outlook for windows this option is available, it is not available in outlook for Mac new look. you should be able to send and email and set a reminder/flag from the mail option ribbon on the new look outlook.

Add support to end appointments & meetings early (25m / 50m) so you have time to prepare for the next meeting. Already supported by Outlook for Windows: https://support.office.com/en-us/article/schedule-a-meeting-with-other-people-5c9877bc-ab91-4a7c-99fb-b0b68d7ea94f

Literally can't even use the new Outlook now since we rely on this

Including every sent mail in a grouped conversation in your mailbox makes the thread very long, and I don't necessarily want to see the messages I've sent. Plus, they're always available to me in the Sent folder. Please go back to grouping only the new items in a conversation sent by others and excluding those sent by the user. Thank you!

Old Outlook had an option to always load images for Contacts. This function has disappeared and adds extra frustration for known-good senders / mailing lists.

There is no feature to support Groups or contact lists in new Outlook for macOS. When you switch from old to new, the Lists are not visible and neither can one create new lists

When I create a new email message and begin typing the name of a contact, Outlook should find contacts from all of my mail accounts. This worked in Old Outlook, but in New Outlook it only searches contacts in the current account.

Make it possible to sort the saved search folder just like and between the favorite folders.

Add the MyAnalytics insights to the new Outlook for Mac.

I suggest you add a button to create a task from an email body that is highlighted. When a text is highlighted you should be able to create a task quickly from there with being able to link back to the original email as a reference.Inviting people to a task would be a nice touch as well.

It would be nice to be able to hide the search bar at the top. It wastes a lot of space on the screen, and I don't use it all that frequently. A show/hide option would be great, and a keybind to search something when it is hidden would be even better!

Support for Tasks view

Instead of saying "Yesterday" it would say the date and time in the reading pane: i.e. 10/01/2020 11:41PM. This is useful if you are getting Nagios alerts from your monitoring system so you know what time an outage happened.

Please add an option to use HTML. I know how to make text and images "link" to a website, but I want to add images, from HTML references in my email signature so I can use logos from a website and not be forced to attach the image to an email.

Contrary to Outlook for Windows, I can only include raw links to OneDrive documents, inline my text, with unfriendly URLs. I would prefer Outlook for Mac to make the attachment look like a normal attachement like it does for Windows, as well as automatically add permission to recipients

Not able to sort by Flag - clicking on column does not work, menu option is not there

You can change meeting length by dragging the outside of the event in calendar. You should be able to adjust in 15 minute intervals. Instead I have to type in the 15 minute offset. Once it is on a 15 minute interval (3:15 or 3:45) you seem to be able to do more but it reverts back if you hit a 30 minute interval

Please give us the ability to subscribe to any url based calendar feeds. I've been able to use the feature in Google Calendar and would love the ability to subscribe to my personal calendars with my work calendars in the Outlook client to have a consolidated view of my different areas of focus.

Unify the email file types between Mac and PC. i.e. use .OTF on Mac instead of .EML. If I create an email template I need to use a virtual machine and run Outlook PC to create an .oft. Why can't I save a .oft on Mac?
